Abstract: In order to clarify the symmetry of sintering parameters under compressive and tensile stresses, uniaxial viscosity measurements were performed for 0.1 mol% yttrium doped ceria under tension and compression, and without and with AC electric field. Major findings are: (i) the strain rate was confirmed to be linear under compressive/tensile loading and electrical fields; (ii) as a result, for a given relative density, the uniaxial viscosity is the same under tension and compression; (iii) the uniaxial viscosity decreases under moderate electrical fields, which implies the effect of electrical fields is not restricted to a specific doping level.
